Holmgang is way too strong for how short the CD is and needs to be nerfed.

That sounds like a huge problem in terms of efficiency since you are not using your abilities and your co-tanks abilities optimally. There is no advantage to using all of your tank CD's on tank busters over invul especially when your tank CD's can be used on auto attacks instead.

I didn't claim it was efficient nor that it's our usual strategy, but I have had to do it out of necessity a few times - my point was mainly it would've been impossible to do the same on ExDeath. In this case the difference is not Holmgang but rather the way the fight is designed.
